Aus dem DE 298 20 796 U1 ist eine Falzmaschine bekannt, die mehrere hintereinander in Bogendurchlaufrichtung angeordnete Falzpaare aufweist, zwischen denen jeweils ein Bogen durchgeführt wird. Eine Falzwalze des ersten Falzwalzenpaars ist stationär angeordnet, während die anderen Falzwalzen zur Bildung eines Falzspaltes mit der anderen Falzwalze des entsprechenden Falzwalzenpaares verstellbar angeordnet ist. Die verstellbaren Falzwalzen sind jeweils durch eine Vorspanneinrichtung in Richtung der stationären Walze vorgespannt. Auf dem Zuführtisch der bekannten Falzmaschine ist eine Dickenmesseinrichtung angeordnet, die die Dicke eines ersten durchlaufenden Bogens misst, der dem ersten Falzwaizenpaar zugeführt wird. Der ermittelte Messwert wird an einen Prozessrechner weitergegeben. Dort werden unter Berücksichtigung eines jeweiligen Falzschemas die notwendigen Falzspaltweiten errechnet. Danach werden die Stellantriebe zur Verstellung der verstellbaren Falzwalzen so lange angesteuert, bis Ist-Werte von Positionsmeldem den errechneten Soll-Werten entsprechen. Korrekturen können sowohl über eine Tastatur als auch über zu den motorischen Antrieben parallel wirkende manuelle Spindelantriebe, die auch auf die Positionsmelder wirken, erfolgen.From DE 298 20 796 U1 a folding machine is known which several consecutively Has folded pairs arranged in the sheet travel direction, between which in each case a bow is performed.

Das erfindungsgemäße Verfahren arbeitet ohne Einzelbogendickenmessung und fehlerhafte Spaltweitenberechnung. Es können außerdem Lufteinschlüsse, die Bogenzusammendrückung, der Walzenverschleiß sowie die Walzenverschmutzung berücksichtigt werden. Eine Korrektur der Falzspaltenweiten ist durch eine entsprechende Ansteuerung der Antriebe durch eine Prozesssteuerung möglich, wobei die Korrekturwerte von einem Bedienterminal, z.B. einer Tastatur eingegeben werden können.Since in the inventive method, the Falzspaltenweite in the passage of a Arc is measured on all pairs of folding rollers and the Falzwalzenspalt then by the associated drive at each pair of folding rollers accordingly is set to the acquired measured values, is no complicated calculation of Folding gap widths depending on a thickness measurement required, as in the known from DE-298 20 796 known prior art is the case. The invention Method works without single sheet thickness measurement and faulty Gap width calculation. In addition, air pockets, the sheet compression, the roll wear and the roll contamination considered become. A correction of the Falzspaltenweiten is by a corresponding control the drives by a process control possible, the correction values from an operator terminal, e.g. a keyboard can be entered.

Dem ersten bis vierten Falzwalzenpaar ist jeweils eine Falztasche 24 bis 30 nachgeordnet.The first to fourth pair of folding rollers each have a folding pocket 24 to 30 downstream.

Die Verstellbarkeit der Falzwalzen 14 bis 22 wird nachstehend anhand der zweiten Falzwalze 14 näher erläutert. Die Falzwalze 14 ist an dem freien Ende eines Armes 34 eines zweiarmigen Lenkers 33 drehbar gelagert, der um eine maschinenfeste Achse 36 verschwenkbar ist. An dem zweiten Arm 35 des Lenkers 33 greift eine Druckfeder 38 an, durch die die Falzwalze 14 in Richtung der Falzwalze 12 vorgespannt wird. Der zweite Arm 35 des Lenkers 33 ist darüber hinaus zur Verstellung der Falzspaltenweite zwischen den Falzwalzen 12, 14 kinematisch mit einem Stellglied 42 verbunden. Außerdem ist dem Lenker 33 ein Wegmesssystem 40 zugeordnet, das die Auslenkung ΔS des Lenkers 33 misst.The adjustability of the folding rollers 14 to 22 will be described below with reference to the second Folding roller 14 explained in more detail. The folding roller 14 is at the free end of an arm 34 of a two-armed arm 33 rotatably mounted, which is a machine-fixed Axis 36 is pivotable. On the second arm 35 of the handlebar 33 engages a Compressive spring 38, biased by the folding roller 14 in the direction of the folding roller 12 becomes.

Gleichzeitig werden vom Prozessrechner 44 alle auf die Lenker 33 wirkenden Stellglieder 42 so angesteuert, dass die Falzwalzen 12 bis 22 der einzelnen Falzwalzenpaare miteinander in Kontakt kommen, so dass die Weite der Falzwalzenspalte "0" beträgt. Dabei werden die Lenker 33 durch die Druckfedern 38 in Richtung der anderen Falzwalze des Falzwalzenpaares vorgespannt.For automatic adjustment of the Falzwalzenspalte be first the actuators 48 of all folding pockets 24 to 30 from the process computer 44 in dependence on desired folding scheme driven and set the folding pockets 24 to 30. At the same time all of the process controller 44 acting on the handlebar 33 actuators 42 driven so that the folding rollers 12 to 22 of the individual folding roller pairs come into contact with each other, so that the width of the Falzwalzenspalte "0" is. In this case, the link 33 by the compression springs 38 in the direction of the other Pre-tensioned folding roller of the folding roller pair.

Bei Verwendung neuer Falzwalzen 12 bis 22 können die Wegmesssysteme 40 so justiert bzw. voreingestellt werden, dass der gemessene Weg der Auslenkung des Lenkers 33 "0" beträgt. Der Wert 0" wird als Referenzwert herangezogen. Wenn bei einer späteren automatischen Einstellung der Falzwalzenspalte die gemessene Auslenkung größer oder kleiner 0 ist, wenn die Falzwalzen in Kontakt gebracht werden, kann hierdurch festgestellt werden, dass die Falzwalzen entweder verschlissen oder verschmutzt sind.When using new folding rollers 12 to 22, the distance measuring systems 40 can so be adjusted or preset that the measured path of the deflection of the Handlebar 33 is "0". The value 0 "is used as a reference value a later automatic adjustment of the Falzwalzenspalte the measured deflection greater or smaller than 0 when the folding rollers are brought into contact, can be found by this that the folding rollers either worn or are dirty.

Zur automatischen Einstellung der Falzspaltenweite wird ein Bogen zwischen das erste Falzwalzenpaar 12, 14 eingeführt und durchläuft das Taschenfalzwerk 10 gemäß dem gewünschten Falzschema. Dabei werden die einzelnen verstellbaren Falzwalzen 14 bis 22 der Bogendicke entsprechend ausgelenkt. Diese Auslenkung entspricht der Weite der Falzwalzenspalte, die für die Bearbeitung nachfolgender Bogen optimal ist. Die Auslenkung wird jeweils durch das Wegmesssystem 40 gemessen und ein entsprechender Messwert an den Prozessrechner weitergegeben. Daraufhin steuert der Prozessrechner 44 die Stellglieder 42 so, dass die zuvor beim ersten Bogendurchlauf durch das Wegmesssystem gemessene Auslenkung eingestellt wird. Ggf. können Korrekturwerte über die Tastatur 46 eingegeben werden. Hierdurch sind für den Durchlauf weiterer Bögen durch das Taschenfalzwerk 10 alle Falzwalzenspalte optimiert.For automatically adjusting the folding gap width, an arc between the first folding roller pair 12, 14 introduced and passes through the pocket folder 10 according to the desired folding scheme. The individual are adjustable Folding rollers 14 to 22 of the sheet thickness deflected accordingly. This deflection corresponds to the width of the Falzwalzenspalte, the following for the processing Bow is optimal. The deflection is in each case by the displacement measuring system 40th measured and passed a corresponding measured value to the process computer. Thereafter, the process computer 44 controls the actuators 42 so that the before first arc passage set by the displacement measuring system measured deflection becomes. Possibly. Correction values can be entered via the keyboard 46. As a result, for the passage of more sheets through the Taschenfalzwerk 10 all Falzwzwenspalte optimized.

Ein eingestellter Wert, der durch einen Musterbogen (1. Bogen) ermittelt wurde, bildet einen Sollwert für die Walzenspalteinstellung. Dieser Sollwert kann im Produktionsprozess ständig mit dem aktuellen Ist-Wert verglichen werden, wodurch es möglich ist, Veränderungen im Falzwalzenspalt (z.B. durch Walzenverschmutzung, Walzenabnutzung, Papierdickenveränderung) sofort im Produktionsprozess festzustellen und anzuzeigen.A set value, which was determined by a pattern sheet (1st sheet) forms a setpoint for the nip adjustment. This setpoint can be in the production process be constantly compared with the current actual value, making it possible is, changes in the Falzwalzenspalt (for example, by roll contamination, roller wear, Paper thickness change) immediately in the production process and display.
